vMy invention moreparticularly relatesto l a mm; which may readily besecured in closand without exceeding thescope of any ,elai ns.

My.inventiomwill best be understood by reference to the accompanyingdrawings, in whichF'gure 1 is an end view of atank ,.car and its dome,partially in section; Fig

Referring now to the drawings,-. '10 is I the ,metal sheet ofatank car,in connection with whioh I .have ,illustrated my invention, and which,in practice, is usuallyhcoveied with heat insulating material. The tankoar is. provided .with the usual dome, indicated? generally atll, andcomprising the'doine sheet 12, which may be covered with suit- 14,preferably oblong, asshown. ,A dome rinolfi the opening of which ispref-' ly somewhat smaller-than the opening 14, is secured to. the innersideoi the' jdome sheet 12 as by rivets 16, said ring being providedwith a downwardlyextending. annu laivflange l 'l, the edgefls, of whichforms a seat for the lcover 19. The said cover is preferably hinged asat 20, t'he cover being provided with a hinge lug or enlargement 21,provided with an elongated opening22, extending transversely of thecover, and adapted to receive a bolt. 23 mounted in lugs 24: and 25(Fig. 2) with which the ring 15 is provided. A projection 42 on cover 19contacts with the stop 43 to prevent the cover from swinging too farinside the re I evenly on tliefiange under all circum as will-readily beunderstood.

7 attached to theoutside of the c 'oepta'rle and contacting witht'heinside wall thereof. gl he oover 19 is provided withan annular seat26,adapted to engage 'the'edge 18 of the flange"17, a suitable gasket 27preferably being'interpose'd between the said seatand the said fiange;.The openingQQ .in the hinge lug preferably elongated in one d rectiontopermit the cover to seat stances, A "fastening eye bolt, is g olverl9, the eye 29 receiving a rivet 3'0, securely rivetecl member 28, hereshownas an in lugs 31 on the upper sideof'th'e cover, so"

,that the fastening member 28 is hinge'dly attached 'tothe cover. Theouter end'oftne fastening member 28".is, provided with a head, in theform of a nut received on the threaded end 32 of the member "28. Thecover is also preferably provided with a lug 34, having an opening-at 35to which a. ;chain may readily be attached foroperating the cover. nQonperatingwith tlie'fastening devicefls s a jinember fi, adapted to bemounted on the fo pe ning1 15, and preferably hingedly ring-is pro edwithyan upwardly extend repli wit a lopen f e 3 ancljatlapted] toQIQCQIVQ. a rivet '39, which oke; member was whijoh the end 10f thejbrijdge me111beiy36flis provided, as best shown inF gzQQ th'e riyet39preferably be:

It will be noted that this operation can be carried outwithout the removal of any parts, such as the nut on the bolt or thecover itself, in the manner that has previously been common, therebyavoiding the possibility of the parts being lost while the cover is inthe open position. To close the cover, the operation is the reverse.

.The cover is raised, with the nut on the bolt in registry with theenlarged portion 41 of the opening, and when the cover is seated, thebolt is moved to the right as viewed in Fig. 3, thereby causing the nutto engage the portion of the bridge member36 surrounding the contractedpart of the opening. It will, of course, be apparent that the nut canreadily be adjusted to compensate for wear between the parts.

I claim:
